Abstract
The invention discloses an achieving method and device of an emergency service. The achieving method and device are used for keeping the emergency service continuously achieved after an SIM/USIM card used in UE is pulled out. The achieving method of the emergency service includes the steps that when a user identification card does not exist in the UE, the UE initiates a Detach adherence process and initiates an Emergency adherence process; the UE reconstructs an IMS Emergency session.
Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of implementation method and device of urgent (Emergency) business.
Background technology
Current third generation collaborative project (3rd Generation Partnership Project, 3GPP) study subscriber equipment and extracted subscriber identification module (SIM Subscriber Identity Module)/USIM (Universal Subscriber Identity Module, USIM) behavior after card, think under this scene, subscriber equipment (User Equipment, UE) need to send out detach request (Detach Request) to network, and enter non-registered (DEREGISTERED) state.
But, the method is not considered to have urgent (the Packet Data Network of (Emergency) Packet Data Network at subscriber equipment, in situation about PDN) connecting, if initiate attachment removal (detach) process, will remove Emergency PDN connection, thereby interrupt the problem of emergency services (Emergency service).
In 3GPP system, Emergency business is divided into packet switching (Packet Switched, PS) the Emergency business of territory (domain) and circuit switching (Circuit Switched, CS) the Emergency business of domain, in PS territory, UE is by IP Multimedia System (IP Multimedia Subsystem, IMS) Emergency session (session) obtains Emergency service, and UE need to set up Emergency PDN and connects to support IMS Emergency session here.3GPP network, based on local rules and carrier policy, can be taked different degrees of support to Emergency business:
A.valid UEs only: only there is the effectively signing UE normally adhering to and can obtain Emergency service.
B.Only UEs that authenticated are allowed: only have the UE by authentication could obtain Emergency service, UE must have effective international mobile subscriber identifier (International MobileSubscriber Identifier, IMSI).
C.IMSI required, authentication optional:UE must have IMSI, and IMSI can be by authentication.By the IMSI of authentication, in network, be not only used as recording use.Network is used IMEI as the sign of UE, only has the UE of International Mobile Station Equipment Identification (International Mobile Equipment Identity, IMEI) to be rejected.
D.All UEs are allowed: all UE, comprise and only have the UE of IMEI and IMSI not by the UE of authentication, now IMEI is as the sign of UE.
According to the residing domain of UE, detach process is divided into evolved packet system (the Evolved Packet System of PS domain, EPS) the IMSI detach of/GPRS (General Packet Radio Service, GPRS) detach and CS domain.
UE initiates EPS/GPRS detach by send out Detach request message to network;
UE initiates IMSIdetach process by send out IMSI DETACH indication (INDICATION) message to network.
UE can also initiate this locality (local) detach process and carry out local detach, and local detach does not need to send to network the signaling message of demonstration.
In sum, if subscriber equipment exists Emergency business, after the SIM/USIM of UE card is extracted, if allow UE from network detach, the Emergency PDN of UE connects and will be interrupted so.Particularly network support provides Emergency business to all UE, i.e. network support does not have the UE of IMSI to obtain the situation of Emergency business, and the Emergency business of UE can not be guaranteed.
